I'm Stuart L. Hart, a leading authority on the implications of environment and poverty for business strategy. A few years ago, I defined the concept of sustainable value; my work includes over 70 academic papers and several books.

With C.K. Prahalad, I wrote the pathbreaking article: The Fortune at the Bottom of the Pyramid which provided the first articulation of how business could profitably serve the needs of the four billion poor in the developing world.
